Hybrid tea rose plant named `Jacheir`

ABSTRACT

A hybrid tea rose plant having deep red-purple flowers of good hybrid tea form, strong fragrance, glossy green foliage and excellent plant vigor.

The present invention relates to a new and distinct variety of roseplant of the hybrid tea class which was originated by me by crossing anunnamed seedling with the variety "Heirloom" (U.S. Plant Pat. No.3,234).

The primary objective of this breeding was to produce a new rose varietyhaving the good bud form, vigor and disease resistance of the femaleunnamed, lavender pink, hybrid tea seedling combined with the deeplavender purple flower color and fragrance of the hybrid tea male parent"Heirloom." The objective was substantially achieved, along with otherdesirable improvements, as evidenced by the following unique combinationof characteristics that are outstanding in the new variety and thatdistinguish it from its parents, as well as from all other varieties ofwhich I am aware:

1. Deep red-purple flowers of good form;

2. Strong fragrance;

3. Glossy green foliage; and

4. Excellent vigor.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing and all other characteristicsand distinctions come true to form and are established and transmittedthrough succeeding propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.
